Description

Dispenser for pre-cut wipes, method of implementation and method of adjustment of such a dispenser

technical field

The present invention relates to a dispenser for pre-cut wiping material. The invention also relates to a method of implementing and adjusting such a dispenser.

Background technique

The field of the invention is that for dispensing pre-cut wiping materials in specific formats, such as towels, paper towels, or similar products. This material can be paper, cellulose wadding, or any other material suitable for the desired application. This material is positioned in the dispenser in the form of a roll. The reel unwinds a strip of the material, after which the strip is directed to the outside of the device so that it can be accessed by the user.

The applicant has designed various devices in this field, such as those described in documents FR2960760, FR2966034, FR2968530, FR2986957, FR2992542 and FR2995520.

Contents of the invention

The object of the invention is to improve existing installations.

To this end, the object of the present invention is a dispenser for pre-cut wiping material in the form of a reel that can be unrolled into a strip. The dispenser includes a housing, a cover movable relative to the housing between an open position and a closed position, and a module received in the housing. The module is partially covered by a cover in the closed position and defines an outlet channel for the strip of material. Modules include:

- two side walls parallel to each other, between which the reel is positioned,

- guiding means for guiding the unwinding of the tape from the reel,

- means to pull the belt towards the exit channel,

A baffle transversely disposed between the side walls, the baffle having two side edges extending toward the side walls, and a front surface comprising a rainbow-shaped profile comprising respective edges along the front surface Arc-extended ridges and grooves, and

- a panel arranged transversely in front of the baffle, movable relative to the side walls between a lowered position and a raised position, and having a rear surface comprising a rainbow-shaped profile comprising each along the front Arc-extended ridges and grooves on the surface;

Said rainbow profile on the baffle and the rainbow profile on the plate are complementary such that the ridges of the baffle are received in the grooves of the baffle and the ridges of the plate are received in the grooves of the baffle when the plate is in the raised position middle;

A space for guiding and clamping the strip is thus defined between the baffle and the plate, this space has a variable configuration and is located immediately upstream of the exit channel of the strip;

The modules include a system of relative clearances between baffles and plates to vary the configuration of the space for guiding and clamping the belt, the clearance system consists of:

- four transverse bars, formed projecting from the side edges of the baffle, each side edge having two separate bars, and

- four containers, made in the side walls of the module, two containers per side wall,

Each receptacle receives one of the bars of the baffle, and the receptacle includes a longitudinal portion and a vertical portion, thereby longitudinally and vertically defining a gap between each bar and the corresponding receptacle.

Thus, the invention makes it possible to avoid the retraction and lifting of the strip of material due to the oscillating movement of the guide means. This oscillating motion occurs when a user applies a pulling force to the strip of material at the exit channel. In practice, the greater the pull applied by the user, the more pronounced this oscillating motion becomes.

This gap system makes it possible to temporarily narrow the space defined between the baffle and the plate, thus temporarily increasing the friction exerted between the belt, baffle, and plate in this space when the user pulls on the strip of material force. First, these frictional forces combine with pulling forces to separate a format from the belt. Additionally, these frictional forces also prevent the tape from retracting towards the spool.

This clearance system is effective regardless of the direction of the user-applied pull. The blocking of the retraction of the tape takes place in the space directly above the exit channel, vertically from the clamping and stretching of the format containing the ends of the tape.

When the tape is out of use, the user does not need to look for the tape in the module, thus avoiding troublesome operations. Thus, the present invention provides greater ease of use. The present invention is easy to implement and is effective on all types of wiping materials, regardless of their thickness and specific characteristics.

According to other advantageous features of the invention, considered individually or in combination:

- The gap system also comprises two springs arranged on each side of the module, each spring comprising an upper end hooked to one of the side walls, and a lower end hooked to a rod housed in a container made in the side walls.

- The spring is positioned at an angle and exerts a force tending to return the flap upwards and forwards, and thus vertically and longitudinally narrow the space defined between the flap and the plate.

- The spring is positioned longitudinally and exerts a force tending to return the baffle forwards and thus longitudinally narrows the space defined between the baffle and the plate.

- The spring is positioned vertically and exerts a force tending to return the flap upwards and thus vertically narrows the space defined between the flap and the plate.

- The clearance system comprises springs positioned laterally and which exert a force tending to return the baffle sideways and thus laterally narrow the space defined between the baffle and the plate.

- The gap system comprises adjustment means for the lateral position adjustment of the baffle between the side walls, the adjustment means being actuated by the operator.

- The adjusting means consist of a small plate pressing on one of the bars of the baffle, a screw passing through the small plate and penetrating into one of the side walls of the module; a screw screwed into the side wall presses the small plate on the bar, moving The baffle and laterally adjust the space defined between the baffle and the board.

- the adjustment device comprises: a thread formed on one of the bars of the baffle, a bolt positioned on the bar, a spring inserted between the bolt and one of the side edges of the module; a bolt screwed on the bar compresses the spring, The rod and baffle are moved and the space defined between the baffle and plate is adjusted laterally.

- The module comprises means for pulling the belt through the space defined between the baffle and the plate towards the outlet channel.

The object of the invention is also a method of implementing a dispenser as described above, when the user exerts a pulling force on the strip at the exit channel, a frictional force of friction is applied to the mechanism for guiding and clamping the strip. Between the belt, baffle and plate in the space; in the first stage, friction is combined with pulling force to force a format to separate from the belt, after which in the second stage friction prevents the belt from moving backwards.

The object of the invention is also a method of adjusting the dispenser as described above, when the operator positions a new reel in the module, the thickness, pre-cut and/or composition material of the reel is the same as the previous one used in the dispenser The reel is different, after which the operator actuates the adjustment device to widen or narrow the space defined between the baffle and the plate, and performs different pull tests on the belt at the outlet opening in order to define the optimum pull for the belt, which The optimum tension is a function of the configuration of the space defined between the baffle and the plate.

Typically, actuation and pull testing of the adjustment device is iterative until a satisfactory pull is achieved.

Detailed ways

Figures 1 to 10 show a dispenser 1 of pre-cut wiping material in the form of a reel B which can be unrolled into a strip S.

The overall operation of the dispenser 1 is described, for example, in FR2986957. The features of the present invention will be specifically described below.

For spatial reference purposes, the vertical direction is defined as top to bottom, the longitudinal direction is defined as front to rear, and the lateral direction is defined as left to right.

The dispenser 1 comprises a housing 2 , a cover 3 and a module 4 . The housing 2 is intended to be attached to a support, for example to a wall. The housing 2 defines a container for housing the module 4 . Cover 3 is hinged on the bottom of housing 2 . The cover 3 is movable relative to the housing 2 between an open position and a closed position. When the cover 3 is in the open position, the module 4 is positioned in the housing 2 . The module 4 is partially covered by the cover 3 when the cover 3 is in the closed position. The lower part of the module 4 is provided with an outlet channel P for dispensing the tape S outside the dispenser 1 .

The module 4 comprises two side walls 5 , guiding means 6 , pulling means 7 , baffles 8 and a front plate 9 . A space E for guiding and clamping the strip S is defined between the baffle 8 and the plate 9 . The configuration of the space E is variable, depending on the relative position between the baffle 8 and the plate 9 . The space E is located immediately upstream of the outlet channel P for the strip S.

The walls 5 are substantially flat and parallel to each other. The reel B is located between the walls 5 at the rear of the module 4 . Reel B is mounted between two stakes, which are not shown in the figure for the sake of simplicity. Each wall 5 includes two containers 56 for supporting the baffles 8 .

Guide means 6 are used to guide the reel B unrolled into the strip S into the space E between the walls 5 . The device 6 comprises two side arms 61 and a transverse shaft 62 supported at both ends by the arms 61 . The shaft 62 supports the belt S. As shown in FIG. The arm 61 swings over the wall 5 so that the shaft 62 can move over the baffle 8 and the plate 9 , and thus over the space E. As shown in FIG.

The pulling device 7 is used to pull the strip S through the space E towards the exit channel P, especially when the strip S is torn too high and cannot be accessed at the exit channel P. The device 7 comprises two side arms 71, a roller 72, a lever 73, and mechanisms not shown in the figure for the sake of simplicity. Further details of the device 7 are described in FR2986957.

Due to the invention, the presence of the means 7 in the module 4 is optional.

Baffles 8 are arranged laterally and vertically between the side walls 5 . The baffle 8 comprises a front surface 81 , a rear surface 82 , an upper edge 82 , a lower edge 83 and two side edges 85 . The front surface 81 is arranged to face the plate 9 and the rear surface 82 is arranged to face the reel B. As shown in FIG. The side edge 85 extends substantially vertically, facing the side wall 5 . Lower edge 84 includes a central opening 87 .

Protruding from the side edge 85 are formed four transverse bars 86 . More specifically, each edge 85 comprises two separate bars 86 , respectively located in the upper and lower parts of the baffle 8 . The rod 86 is housed in the wall 5 behind which the baffle 8 is supported.

Front surface 81 includes a rainbow-shaped profile 88 consisting of alternating ridges 881 and grooves 882 . Each ridge 881 and groove 882 extends along an arc on the front surface 81 . The profile 88 has two lower ends 883 that are open at the edge 85 .

On both sides of the opening 87 the flap 8 comprises a forwardly pointing tip 89 . Point 89 is used to facilitate tearing of pre-cut strip S. Thus, the user pulls the strip S to obtain a single piece of material, leaving the remaining strip S in the space E.

As a variant not shown, the tip 89 can be provided on an add-on, attached to the flap 8 at the opening 87 .

According to another variant, the tip 89 may be replaced by an element of viscous material, for example an elastomer, locally increasing the friction between the strip S and the baffle 8 .

A plate 9 is arranged transversely in front of the baffle 8 and is hinged on the wall 5 . The plate 9 is movable relative to the wall 5 between a lowered position and a raised position. Plate 9 comprises a front face 91 , a rear face 92 , an upper edge 93 , a lower edge 94 and two side edges 95 . When the plate 9 is lifted, the front surface 91 is arranged to face the user of the dispenser 1 , while the rear surface 92 is arranged to face the flap 8 . A hinge 96 is formed between the edges 94 and 95 on both sides of the plate 9 for hingedly attaching it to the wall 5 . Lower edge 94 includes a central opening 97 .

Rear surface 92 includes a rainbow-shaped profile 98 consisting of alternating ridges 981 and grooves 982 . Each ridge 981 and groove 982 extends along an arc on rear surface 92 . The profile 98 has two lower ends 983 that are open at the edge 85 .

On either side of the opening 97 , one of the ridges 981 increases in width at each end 983 . This ridge 981 thus forms a tip 983 facing the baffle 8 . Like tip 89, tip 983 is used to facilitate tearing of pre-cut strip S. Thus, the user pulls the strip S to obtain a single piece of material, leaving the remainder of the strip S in the space E.

As a variant not shown, the tip 983 can be provided on an add-on, fastened to the plate 9 at the opening 97 .

According to another variant, the tip 983 may be replaced by an element of viscous material, such as an elastomer, locally increasing the friction between the strip S and the plate 9 .

Central openings 87 and 97 are located facing each other. The openings 87 and 97 define an outlet passage P immediately below the space E when the plate 9 is lifted.

Rainbow profiles 88 and 98 are complementary. When the plate 9 is lifted, the ridge 881 is received in the groove 982 and the ridge 981 is received in the groove 882 . A space E for guiding and clamping the strip S is defined between the profiles 88 and 98 .

According to the invention, the module 4 comprises a system of relative gaps 10 between the baffles 8 and the plates 9 which alters the configuration of the space E for guiding and clamping the strip S.

The gap system 10 has four receptacles 56 made in the wall 5 and four rods 86 formed protruding from the edge 85 of the baffle 8 . Each receptacle 56 houses one of the rods 86 .

Each container 56 has a non-circular cross-section. More specifically, each container 56 has an L-shaped section, comprising a longitudinal portion 57 and a vertical portion 58 . Thus, a gap is longitudinally and vertically defined between each rod 86 and the inner edge of the corresponding container 56 .

Thus, the baffle 8 can move longitudinally and vertically between the walls 5 . This movement is limited by the abutting contact between the rod 86 and the edge of the container 56 .

The gap system 10 also includes two springs 100 arranged on each side of the module 4 , bearing against the outer surface of the wall 5 . Each spring 100 has an upper end 101 and a lower end 102 . End 101 is hooked to a protrusion 59 formed on wall 5 and end 102 is hooked to one of the rods 86 of flapper 8 .

The spring 100 is positioned at an angle. The spring 100 exerts a force tending to return the flap 8 upwards and forwards, and thus narrows the space E defined between the flap 8 and the plate 9 vertically and longitudinally.

As a variant not shown, the spring 100 is positioned longitudinally. The spring 100 then exerts a force tending to return the shutter 8 forward and thus narrows the space E longitudinally.

According to another variant, not shown, the spring 100 is positioned vertically. The spring 100 then exerts a force tending to return the shutter 9 upwards, and the space E narrows vertically.

According to another variant, not shown, system 10 does not contain spring 100 . In this case, the space E is narrowed by gravity under the weight of the baffle 8 itself.

Preferably, the gap system 10 comprises adjustment means 110 for adjusting the lateral position of the baffle 8 between the walls 5 .

Since the container 56 penetrates the wall 5 , the rod 86 can move laterally in the container 56 . Thus, the baffle 8 can move laterally between the walls 5 . This movement is limited by the abutting contact between the edge 85 and the wall 5 . In other words, the gap provided between each rod 86 and the corresponding container 56 is also transverse.

Adjustment device 110 may be actuated by an operator. The adjusting device 110 includes a small plate 111 and a screw 112 . The small plate 111 presses on one of the rods 86 of the baffle 8 . Preferably, the small plate 111 includes a recessed cavity for receiving the rod 86 . Screws 112 pass through small plate 111 and into wall 5 . The small plate 111 is pressed against the rod 86 by the act of screwing the screw 112 into the wall 5 . The baffle 8 moves laterally, adjusting the space E between the baffle 8 and the plate 9 laterally.

In practice, the gap system 10 makes it possible to temporarily narrow the space E defined between the fence 8 and the plate 9, thus temporarily increasing the strip S, fence 8 in this space E when the user pulls on it. , and the friction force applied between the plate 9. Friction combined with tension forces a format to separate from strip S in space E. This format is then pulled from the exit channel P by the user. In addition, friction prevents the strip S from moving backwards back to the reel B by clamping the strip S in the space E.

11 to 13 show other embodiments of the present invention. Certain elements are parts of the dispenser 1 that are comparable to those of the first embodiment described above, the same reference numerals being used for the sake of simplicity.

In FIG. 11 , the adjustment device 110 comprises a thread 116 formed on one of the bars 86 of the baffle 8 , a bolt 117 positioned on this bar 86 , and a screw inserted between the bolt 117 and the edge 85 of the baffle 8 . Spring 118. By the act of screwing the bolt 117 on the rod 86, the spring 118 compresses on the edge 85 and the rod 86 moves laterally. The baffle 8 moves laterally, adjusting the space E between the baffle 8 and the plate 9 laterally.

In FIG. 12 , the lower end 883 of the rainbow-shaped profile 88 is oriented at 45 degrees and does not open at the edge 84 . Similarly, lower end 983 of rainbow-shaped profile 898 is oriented at 45 degrees and does not open at edge 94 .

In Figure 13, only the baffle 8 is shown, and the end 883 is also oriented at 45 degrees. The profile 88 has a curved upper portion 885 and two straight upper portions 886 .

In the embodiment of Figures 12 and 13, the space E has a different configuration, but the cutting of the strip S is at least as effective as compared to the first embodiment described above.

In practice, the dispenser 1 may have a different configuration than that of FIGS. 1 to 13 without departing from the scope of the present invention. In addition, the technical features of the different embodiments and variants described above may be combined in whole or in part. Thus, the dispenser 1 can be adjusted in terms of cost, ergonomics, functionality and performance.
